Original GitHub issue: https://github.com/FiloSottile/mkcert/issues/234

I want to create a certification for a host with a specific port:

mkcert "localhost:4447"

On execute this following command, we get this following result:

Using the local CA at "/Users/truongnmt/Library/Application Support/mkcert" ✨
ERROR: "localhost:4447" is not a valid hostname, IP, URL or email

You can't include a port in the name - this support doc explains it quite well. To quote:

The common name is not a URL. It doesn’t include any protocol (e.g. http:// or https://), port number, or pathname.
